'SWQAGE-YBLOCK.

SPECIFICATION forming part of Letters Fatent No. 727,885, dated May 12,1903. Application filed October 3, 1902- Serial No. 125,765. (No model.)

To all whom it may concern:

Be it known that I, HORACE BENJAMIN BLOOD, a citizen of the UnitedStates, and a resident of Rochester, in the county of Monroe and Stateof New York, have invented a new and Improved Swage-Block, of which thefollowing is a full, clear, and exact description.

The invention relates to swage-blocks such as shown and described inLetters Patent of the United States No. 700,724, granted to Benjamin F.Blood on May 27, 1902.

The object of the invention is to provide a new and improved swage-blockdesigned for the use of blacksmithsand other iron-workers and arrangedto permit of securely clamping the anvil in the desired position and to.

allow of a quick release of the anvil-whenever it is desired to adjustthe anvil to a different position. I

The invention consists of novel features and parts and combinations ofthe same, as

will be more fully described hereinafter and then pointed out in theclaims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a perspective view of the improvement. Fig. 2 is a plan Viewof one end of theimprovement, parts being shown in sec-' Fig. 3 is aperspective view of part of tion. the clamping device. Fig. i is a sideelevation, partly in section, of a modified form of the improvement.Fig. 5 is a similar view of another modified form of the improvement.

Fig. 6 is a like view of another modified form or secured on the top ofstandards D D, conected with each other at their lower ends by ods E, asplainly shown in Fig. 1. A clampto, so that further description calrecesses D for engagement by the ends of the anvil to hold the same ineither a horizontal or vertical position at the time the standards D andD are drawn together by the clamping device, the same as shown anddescribed in the Letters Patent above referred thereof is not deemednecessary.

The rod F of the clamping device carries at one end a crank arm orhandle G under the control of the operator, and on the other end of therod is formed a screw-thread F, screwing in a not H, the rod passingloosely through a bearing H. The bearing H and not H are removably heldin the cross-bars D D of the standardsDand D, the said bearing and notbeing providedwith notches fitting into forks in the cross-bars to holdthe bearing and nutagainst longitudinal movement, but to allow oflifting them out of the cross-bars wheneverit is desired to disconnectthe clamping device from the standards- Now by turning the handle G inthe proper direction a rotary motion is given to the rod F to screw thesame in the nut H,-'and as the shoulder of the handle G comes in contactwith the outer face of the bearing H the hearing and nut andconsequently the standards D and D are drawn towardeach other.

In order to quickly release the ends of the anvil A from the standards Dand D at the time the upper ends thereof are moved apart, I interposesprings I and 1 between theends of the journals B B and lugs C C formedon the bearings C O, the outer ends of the springs I and I being held onpins 0 projecting from the inner faces of the lugs 0 C and the innerends of the said springs are set in recesses formed in the ends of thetrunnions or journals B B, as plainly indicated in Fig. 2. Now when theends of the standards D D are drawn together by a corresponding actionof the clamping device then the springs I and l are compressed and thepins G" pass in to the openings in the trunnions to hold the latter andconsequently the anvil A against upward movement in. the bearings C 0.As soon as the clamping device is actuated to move the upper ends of thestandards D D apart then the springs I I exert their pressure on thetrunnions and standards to immediately disengage the ends of the anvilfrom the inner faces of the standards to allow convenient turning ofthe'anvil to another position. This result may also be obtained by othermeans-for instance, as shown in Fig. 4, by the use of flanges B formedon the ends of the trunnions 01' journals E the said flanges beingadapted to engage shoulders D on standards D so that when the standardsmove apart the corresponding shoulder D, engaging a flange B pulls theanvil A with it, so as to move the opposite end of the anvil out ofengagement with the opposite standard. The end of the journal B isformed with an opening B, adapted to be engaged by a pin 0 on a lug 0either integrally formed on the standard D as shown in Fig. 4, or boltedthereto, as indicated in Fig. 6.

In the modified form shown in Fig. 5 the anvil A is formed with conicaltrunnions B engaging correspondinglyshaped bearings C on the standards Dso that when the upper ends of the standards are moved apart thetrunnions slide down the bearings C thus moving the ends of the anvilout of contact with the inner faces of the standards. Vhen the upperends of the standards I) are drawn together, then the trunnions B rise,and their apex ends engage lugs 0 formed on the bearings C toholdthetrunnions,and consequently the anvil, against upward movement.

The clamping device shown in Fig. 8 consists of a rod F having one end Fpolygonal and secured in a corresponding opening in the cross-bar D ofone of the standards by heads F, held on the said end F and abuttingagainst the faces of the said cross-bar. The other end F is threaded,and on this end screws a handled nut G, under the control ,of theoperator and arranged to abut against the outer face of the othercross-bar D on the opposite standard, and the said end F extends throughan elongated aperture D in the said cross-bar. A spring J is coiled onthe threaded end F and rests with one end on a collar F, secured to therod F the other end of the spring abutting against the inner face of thecross-bar. Now by screwing up the nut G on the end F against thecrossbar D the standards are drawn toward each other, and at the sametime the spring J is pressed, and when the nut G is screwed outward onthe end F then the standards are pressed apart by the action of thespring J.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A device of the class described, comprising aframe having standards connected with each other at their lower ends,open bearings in the upper ends of the said standards, an anvil havingjournals engaging the said open bearings, a clamping device for movingthe upper ends of the standards toward each other, to engage thestandards with the ends of the anvil, and resilient means for separatingthe standards and the ends of the anvil on opening the clamping deviceto permit the anvil to turn freely on its trunnions, as set forth.
